This happens when ixgbevf supporting mailbox API 1.6 cooperates\nwith PF driver which doesn't support this version of API, and hence\ndoesn't support new approach for getting PF link data.\n\nIn that case VF asks PF to provide link data but as PF doesn't support\nit, returns -EOPNOTSUPP what leads to early bail from link configuration\nsequence.\n\nAvoid such situation by using legacy VFLINKS approach whenever negotiated\nAPI version is less than 1.6.\n\nTo reproduce the issue just create VF and set its link up - adapter must\nbe any from the E610 family, ixgbevf must support API 1.6 or higher while\nixgbevf must not.\n\nFixes: 53f0eb62b4d2 (\"ixgbevf: fix getting link speed data for E610 devices\")\nReviewed-by: Aleksandr Loktionov <aleksandr.loktionov@intel.com>\nReviewed-by: Piotr Kwapulinski <piotr.kwapulinski@intel.com>\nReviewed-by: Paul Menzel <pmenzel@molgen.mpg.de>\nCc: stable@vger.kernel.org\nSigned-off-by: Jedrzej Jagielski <jedrzej.jagielski@intel.com>\n---\nv2: extend the commit msg (Paul)\n---\n drivers/net/ethernet/intel/ixgbevf/vf.c | 3 ++-\n 1 file changed, 2 insertions(+), 1 deletion(-)", "diff": "diff --git a/drivers/net/ethernet/intel/ixgbevf/vf.c b/drivers/net/ethernet/intel/ixgbevf/vf.c\nindex 29c5ce967938..8af88f615776 100644\n--- a/drivers/net/ethernet/intel/ixgbevf/vf.c\n+++ b/drivers/net/ethernet/intel/ixgbevf/vf.c\n@@ -846,7 +846,8 @@ static s32 ixgbevf_check_mac_link_vf(struct ixgbe_hw *hw,\n \tif (!mac->get_link_status)\n \t\tgoto out;\n \n-\tif (hw->mac.type == ixgbe_mac_e610_vf) {\n+\tif (hw->mac.type == ixgbe_mac_e610_vf &&\n+\t hw->api_version >= ixgbe_mbox_api_16) {\n \t\tret_val = ixgbevf_get_pf_link_state(hw, speed, link_up);\n \t\tif (ret_val)\n \t\t\tgoto out;\n", "prefixes": [ "iwl-net", "v2" ] }
